如何检查windows用户是否设置了密码? [英] How to check if windows user has a password set?

问题描述

问题

我不知道这会很难弄清楚，但我来了.

I didn't know it would be this difficult to figure out but here I am.

我正在开发一个网络支持客户端，它必须检测当前登录的用户是否设置了密码.我尝试使用 WMI 检查 Win32_UserAccount 类中的 PasswordRequired 属性，但它返回 false 即使我的帐户是 密码保护.我没有想法...

I'm developing a net support client which has to detect if the current logged in user has a password set. I tried it with WMI checking the PasswordRequired property in the Win32_UserAccount class, but it returns false even if my account is password protected. I'm out of ideas...

(背景:我需要此信息来告诉用户他必须设置一个，以便我可以通过远程桌面连接到他，如果帐户不受保护"，这不是很高兴.如果有办法获得围绕这一点，我也接受不同的解决方案.)

(Background: I need this info to tell the user he has to set one so I can connect to him via remote desktop, which isn't very happy if the account is "unprotected". If there is a way to get around this I'd also accept a different solution.)

解决方案

比我想象的更容易，我使用 WinAPI 函数 LogonUser 管理它并为您提供这个简单的包装代码:

Easier than I thought, I managed it with the WinAPI function LogonUser and provide you this simple wrapper code:

    private bool PasswordRequired
    {
        get
        {
            IntPtr phToken;

            // http://www.pinvoke.net/default.aspx/advapi32/LogonUser.html
            bool loggedIn = LogonUser(Environment.UserName,
                null,
                "",
                (int)LogonType.LOGON32_LOGON_INTERACTIVE,
                (int)LogonProvider.LOGON32_PROVIDER_DEFAULT,
                out phToken);

            int error = Marshal.GetLastWin32Error();

            if (phToken != IntPtr.Zero)
                // http://www.pinvoke.net/default.aspx/kernel32/CloseHandle.html
                CloseHandle(phToken);

            // 1327 = empty password
            if (loggedIn || error == 1327)
                return false;
            else
                return true;
        }
    }

推荐答案

为什么不直接尝试使用空密码登录用户?

Why not just to try to LogonUser with empty password?
